Fast, Reliable General Contractor Across Home Gardens
Finding a general contractor in Home Gardens means navigating something most homeowners don’t realize until the first permit application: this unincorporated Riverside County community sits right in the middle of Corona, and your project’s permitting path depends on exactly which side of the street you’re on. We handle that split every week. Milpitas Construction brings full-scope remodeling, additions, roofing, and ADU construction to Home Gardens homeowners under one contract and one point of contact, headed by Ken Stafford. If you’re planning a kitchen remodel on San Jacinto Street or a room addition off Magnolia Avenue, call (877) 752-4194 for a free estimate.
Why Milpitas Construction Is Home Gardens’s Preferred General Contractor Company
Home Gardens homeowners hire us because we already know what their houses hide. The housing stock here is mid-century and 1960s-70s single-family homes, and nearly every project we take on in the 92879 zip code involves opening a wall and finding something the previous owner never permitted. We plan for that from day one. Our approach is built around a thorough pre-construction inspection followed by a written scope that spells out allowances for hidden conditions, so you’re not guessing what a surprise might cost.
We’ve worked from the streets that back up to the Prado Dam spillway all the way over to the Magnolia Avenue corridor, and the county-versus-city permit question is the first thing we resolve on every Home Gardens job. That local knowledge keeps your timeline from stalling before demo even starts. When you call, you talk to a team that knows whether your address falls under Riverside County Building & Safety or City of Corona review, and we confirm it in writing before we file anything.
Ken Stafford leads every project with a simple rule: no change order gets priced after the fact. If we find undersized framing or outdated wiring once walls are open, the price and the revised draw schedule go in front of you before we touch the next stud.
Styles & brands we work with







Residential General Contractor in Home Gardens
Residential General Contractor work in Home Gardens covers the full scope of what these older homes actually need: kitchens and baths that date to the 1970s, detached garages begging to become ADUs, and room additions on lots that can handle the extra square footage. A typical kitchen remodel in Home Gardens runs $14,000 to $45,000 depending on cabinet grade and countertop selection. A bathroom remodel lands between $9,000 and $28,000. Home additions start around $45,000 and can reach $130,000 when the scope includes foundation work and systems upgrades.
Every project starts with a permit jurisdiction check. That’s not a formality here; it’s the difference between a clean start and a red-tagged plan.
Room Additions and Garage Conversions
Home Gardens parcels tend to be generous for their age, which makes room additions practical. We handle everything from foundation to roofline, including the panel upgrade that older home additions almost always trigger once the county or city inspector looks at the existing service.
Garage conversions are common here, with costs from $30,000 to $80,000. Detached garages on mid-century lots convert well to ADUs, but unpermitted prior electrical work is a regular discovery. We write the allowance for it up front.
Kitchen and Bath Remodeling
Home Gardens kitchens are full of original cabinetry and the kind of wiring that makes a 2026 inspector raise an eyebrow. We spec cabinetry from KraftMaid and Wellborn, and counters from Cambria, Silestone, and Caesarstone. You choose from contractor-grade tiers, not big-box aisles.
Bathrooms get the same treatment, with Kohler and Grohe fixtures as the standard conversation. These brands hold up to Riverside County’s hard water better than off-brand alternatives.
Hire a General Contractor in Home Gardens
Hire a General Contractor in Home Gardens when your project touches more than one trade. The moment a remodel requires plumbing, electrical, framing, and finish work, you need single-contract accountability. You don’t want to coordinate a plumber who blames the electrician who blames the framer. You want one contractor who owns the whole thing.
For Home Gardens specifically, that accountability matters even more because of the permitting split. The same company managing your roof replacement and your kitchen remodel should also know which jurisdiction reviews your window replacement. We do.
Exterior Work and Roofing
Triple-digit summers and Santa Ana wind events are hard on Home Gardens roofs. Roof replacement here runs $8,000 to $20,000, and roof repair from $400 to $1,800. We install GAF and CertainTeed roofing systems that are rated for Inland Empire UV exposure.
Paver patios and driveways are the other big exterior play, with paver patio installation at $3,500 to $11,000 and paver driveways from $7,000 to $18,000. We use Belgard, Unilock, and Techo-Bloc pavers, and the shade structures many Home Gardens homeowners add to survive July make these spaces usable year-round.
ADU and Prefab Construction
ADU construction in Home Gardens runs $90,000 to $220,000, and we’re one of the few general contractors in the area that can seriously discuss prefab options from Abodu, Dvele, Mighty Buildings, Boxabl, and Plant Prefab. On these older lots, a detached ADU over the existing garage is often smarter than a conversion; we’ll walk you through both paths.
Trusted Brands We Service in Home Gardens
We spec materials by name, so you know exactly what’s going into your Home Gardens home. Cabinetry comes from KraftMaid and Wellborn. Countertops are Cambria, Silestone, or Caesarstone. Fixtures from Kohler. Roofing from GAF and CertainTeed. Windows and doors from Therma-Tru and PGT. Siding from James Hardie. Every product we quote for a Home Gardens project is something we’ve installed before and would put in our own homes. That’s the advantage of having access to 50-plus brand-name product lines across every major trade: when a homeowner on Home Gardens’s east side wants a specific Silestone profile, we can get it without a supply-chain delay.

AfterCommon General Contractor Problems We See in Home Gardens Homes
- Wrong permit jurisdiction assumptions. Home Gardens homes can fall under Riverside County Building & Safety or City of Corona review depending on the address. Contractors who assume one and file wrong get plans red-tagged, and the correction adds weeks. We confirm jurisdiction before pulling anything.
- Unpermitted prior additions. Older detached garages and hastily added sunrooms are common here, and many were never permitted. Opening a wall can expose electrical work that won’t pass inspection. We document it, price it in writing, and get it corrected before proceeding.
- Undersized framing and failed waterproofing. Mid-century construction standards were different. We’ve seen 2×4 roof framing that barely met code in 1970 and shower pans that failed a decade ago. These discoveries change scope, which is why our contracts include written allowances for exactly this.
- UV-damaged exteriors and failing stucco. Inland Riverside County heat and Santa Ana winds chew through paint and stucco faster than coastal homeowners expect. Exterior work here needs materials rated for sustained triple-digit exposure, not just whatever’s cheapest.

FAQs About General Contractor in Home Gardens
Your permit jurisdiction depends on your exact address. Home Gardens is an unincorporated Riverside County island surrounded by Corona, so some streets fall under county Building & Safety and others under City of Corona review. We confirm your jurisdiction in writing before filing any permit. Call (877) 752-4194 and we’ll check your address in under a day.
Expect the inspector to flag them, which means bringing the work up to current code before signing off on your new project. We handle this by documenting what we find, pricing the correction in writing, and folding it into a revised scope and draw schedule before we proceed. It’s common in Home Gardens and we plan for it from the first walkthrough.
We pause work, document the condition with photos, and issue a written change order showing the exact cost and the revised schedule. Nothing gets touched until you approve it in writing. On a 1962 ranch near Magnolia Avenue, we found unpermitted electrical work and undersized framing during a room addition. We stopped, documented everything, and got approval before upgrading the panel to 200A and proceeding with county inspection sign-off.
A permit ensures the work meets current building code, which protects your home’s value and your family’s safety. Home Gardens homes built in the 1960s and 70s rarely meet today’s electrical, plumbing, or structural standards, and unpermitted work becomes a problem when you sell or refinance. It also protects you if something fails later.
Yes, every Home Gardens project gets a written scope of work and a draw schedule tied to completed milestones before we start. You’ll see exactly what’s included, what allowances exist for hidden conditions, and when each payment is due. Call (877) 752-4194 to schedule your free estimate and walkthrough.
